ABSTRACT

This paper describes a family of crossed-field power-output noise generator tubes, which may be characterized as injected-beam forward-wave devices. They consist of a noisy gun, a drift space, and a crossed-field amplifier which amplifies the noise further and couples it to the external circuit. The frequency range, power, and efficiency are related closely to the crossed-field amplifier characteristics, and thus may be made to be broad-band, or to be narrow-band and tunable, depending on the slow-wave structure. The slow-wave structures used have been meander lines or lumped-constant structures, all supported on beryllia ceramics.
